IQPolls, an interactive polling system designed to measure customer satisfaction, launched in mid-March, but has recently generated a solid bit of attention thanks to its use of interactive public displays in Vilnius to measure happiness of the city inhabitants. Happy Barometer is a simple service designed to offer insights into the collective moods of various cities. For this service, users simply sign-in and then vote. It’s a simple little service powered by IQPolls, but maybe fun to look at and use.

We were tipped off to this story by Aldas Kirvaitis from Cherry Media Group, but this is a project which has obtained some significant international press in the past couple of weeks with stories in CNN and from Reuters.

To find out about IQPolls, I spoke with one of the company’s co-founders, Arturas Jonkus (who created the project with Rytis Lauris), and he filled me in on their investors, their customers, and another project in the works.

Essentially, IQPolls is a public-display service which allows users to register their level of satisfaction using nothing more than a smartphone. It’s one thing to explain the service in writing, but it might be easier to watch the promotional video released by IQPolls, which better outlines the purpose behind this project.

Anyone with a smartphone and internet access can register for the service in less than 2 minutes and then scan the QR code in order to vote. In the video, Jonkus explains that the idea for the project comes from his experience as a university professor, where he found software used to gauge student enjoyment to be unsatisfactory. Frustrated by this problem, he and co-founder Lauris set about creating a service which would allow people to register happiness without having to download any special app or software. They’ve attracted international attention with their use of interactive public displays to register public happiness in Vilnius, and the product was deployed at the LOGIN 2013 conference in Vilnius, in the French fashion magazine L’Officiel, and in the Top Gear Lithuania journal.

Jonkus tells us that the project is backed with 50,000 Euro by Oxygen Venture Capital and that they have generated some buzz around their product, having been selected as a member of Microsoft’s BizSpark program and as a promising startup which will be attending the WebSummit in Dublin at the end of October. Jonkus tells me that in terms of plans, they have set their sights on the British and American conference markets and says that their primary competition at the moment comes from other conference-voting services. They have received interest from American investors, but it’s too early to go into detail.

As far as pricing is concerned, the service can cost from 99 to 249 Euro per month, depending on the size of the audience (full chart available here). They offer a free trial and are willing to negotiate on price, but the difference between the “levels” is in the number of people who can be polled and how many users can simultaneously manage the system. For each level, real-time results are available for offering insight into the mood of the audience.
